That's from sqlite. (Awesome tech, awesome license).
Related snippet from the "Distinctive Features Of SQLite" page[1] from the sqlite project:
The source code files for other SQL database engines typically begin with a comment describing your legal rights to view and copy that file. The SQLite source code contains no license since it is not governed by copyright. Instead of a license, the SQLite source code offers a blessing:
May you do good and not evil May you find forgiveness for yourself and forgive others May you share freely, never taking more than you give.
